The Miracle Sudoku: Rubik's Cube

** TODAY'S PUZZLE **
There have been a whole host of miracle sudokus since Mitchell Lee's original puzzle all those years ago. Most achieve their sparsely-filled grids with extremely complicated, long rulesets. Michael Lefkowitz bucks that trend! Here is an almost entirely blank grid and a SHORT ruleset - the whole thing, which is called Rubik's Cube, is quite mad!!

Have a go at the puzzle here:

Rules:
Normal sudoku rules apply. The white dot separates digits with consecutive values. Cells in the same position in two 3x3 boxes may not contain the same digit. (So eg, r1c1 and r4c4 cannot contain the same digit as these are both in the top left corner of their 3x3 boxes.) 'XYZ' means 'Row X Col Y is digit Z.' If XYZ is true, YZX is also true.


The puzzle Simon mentioned in the introduction is called Region Geometry and it's by Emre Kolotoğlu. If you have some minutes free, you can try it at the link below. We will make this 3hr 36min video available on Patreon in the coming days.
